   REPÈRES DE SAISIE — COLONNES LARGEUR / HAUTEUR
   ---------------------------------------------------------
   Sur un chantier, inverser largeur et hauteur coûte une
   barre entière. Les deux colonnes sont donc distinguées
   par TROIS signaux redondants : la couleur, une bordure
   latérale, et une flèche d'orientation (↔ / ↕).
   La couleur seule ne suffit pas : elle disparaît en plein
   soleil et pose problème aux daltoniens.
